HP Officejet 150 Mobile All-in-one printer seems stuck - how do I clear it's memory should this be necessary? Say 'now printing" when indeed it is NOT! Also will not turn offvcand none of the icons are lit or will work. How do I turn the thing OFF??? What has caused this and how do I stop it happening again? Using bluetooth to connect to my HP Probook computer and has been working just fine until tonight. Only 2 weeks old!!
